I have a Maestro and like it a lot over stock Hubbles on one of my eight dedicated lines. I'ver heard the Porter recommended a lot (which is cryoed Hubble). I wonder what the cost is at CryoPro to do just one of the single outlet Hubble 5361? I hate to say this, but I can hear subtle differences between the two outlets on a duplex. I've not confirmed, but I suspect the outlet with the line hooked to its screw is best as the other is conducting through the tab. The 5361 eliminates this audio nervosa.
